Question : Configuration error in the e-mail system caused the message to bounce between 2 servers

Hi, I have a Windows 2003 Server Enterprise Edition with Exchange. I get an error message that reads like this: A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between 2 recipients: contact your administrator. It only does it randomly and not always to the same outgoing E-Mails. One time it will send ok, the next it will bounce back. All incoming E-Mails seem fine. Any ideas?

Never found a solution, no one has gotten back to me.
